TOYOTA GAZOO Racing confirmed today that it will start the sales of GR Supra GT4 *1, a race car for customer teams, starting from March 2020 to Europe. The sales area will expand to North America in August, and to Japan/Asia in October. TOYOTA GAZOO Racing intends to strengthen its focus on customer motorsport *2 in order to enable motorsport-lovers around the world to participate in races.
The GR Supra GT4 is based on the GR Supra – TOYOTA GAZOO Racingʼs first-ever global model released earlier this year – and is developed and produced by Toyota Motorsport GmbH（“TMG“).
A three-litre in-line six cylinder engine with single twin-scroll turbocharger has been tuned to 320kW *3（430hp）with a 7-speed sports automatic transmission with paddle shift and the mechanical limited slip differential driving the rear wheels. An Akrapovič exhaust system will be fitted and Ravenol will provide first-fill lubricants.
The front splitter and rear wing are made of natural fibre composite, contributing to an overall weight of 1,350kg*3. Following the specification of the GR Supra road car, the front suspension will be MacPherson strut, and rear suspension will be multilink with KW dampers at the front and rear.
The braking system is enhanced through the use of a dedicated brake calliper for racing, six-pot for the front and four-pot for rear, while the car will use Pirelli tyres.
Safety will be a priority and the GR Supra GT4 will be installed with a high-strength roll cage on the lightweight steel body, and an FIA-standard racing seat with six-point seatbelt. The interior will feature a carbon fibre instrumental panel with a display and steering wheel specifically designed for GT4 competition.
The contact company for each region of the GT4 vehicle sales and customer support (including sales for spare parts and engineer support) parts will be the followings; TMG for Europe, TRD U.S.A Inc. (“TRD USA”) for North America, and Toyota Customizing & Development Co., Ltd. (“TCD”) for Japan/Asia. Please contact the listed company for how to apply for purchase.
